Sub issues Options

I installed my 18" kicker impulse with matching amp (kick impulse amp)... I installed it correctly and it worked fine for a month... but just the other day, I was listening to it, it sounded fine... I turned off the car... and later that day, when I turned my car back on, the sub wouldn't work. No sound comes out of it unless I turn the volume WAY up and turn the sub volume on max. What happens then is it feels like there's not enough power and it sounds like ****... I've been reading and it might be a voice coil... but i dont think i blew the speaker entirely.

I checked the fuses, both of the metal resistors seem to be intact and all the connections seem to be solid.

I'm puzzled.

first thind I would do is to lower the gain on the amp and test a different speaker to see if the amp is working properly.

second, connect the box to a different amp, if you dont have another amp just ask one of your friends. test the box.

Now you isolated the amp from the speaker box.

going by what you described the capacitor will not help you at all. It is to release big amout of power when is needed. this does not sound like the problem you mentioned.

Speakers do not get blown unless you are applying a ton of power into a speaker, the main reason for a speaker to be blown is distortion...

do you have a X-over going into the sub cuting off the mid and hi frequencies or are you running it at full range ? if you are running them at full range there is a possibility that the cone was damaged....
